It now regularly funds nonprofits that are, among other things, hostile to labor unions, skeptical of climate change or critical of the loosening of sexual mores in American culture.

This was first time in more than three decades that a federal court ruled for the plaintiffs in a partisan-gerrymandering suit after a full trial. It also dealt a critical blow to a very particular kind of gerrymander—call it “extreme seat-maximization”—that emerged in Wisconsin and a handful of other states in the most recent redistricting cycle.
